Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 14905-56-7 AR-1L2409 propyl 6-deoxyhexopyranosyl-(1->6)-[pentofuranosyl-(1->2)hexopyranosyl-(1->2)]hexopyranoside.
CATO supplies 14905-56-7 AR-1L2409 propyl 6-deoxyhexopyranosyl-(1->6)-[pentofuranosyl-(1->2)hexopyranosyl-(1->2)]hexopyranoside (CAS 14905-56-7), a certified reference material (molecular formula C26H46O19, MW 662.63 g/mol) for analytical method development and quality control.
Structurally, 14905-56-7 AR-1L2409 propyl 6-deoxyhexopyranosyl-(1->6)-[pentofuranosyl-(1->2)hexopyranosyl-(1->2)]hexopyranoside (C26H46O19) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 662.63 g/mol, it falls into the high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
